英文摘要
We did a systematic research on the singularity theory of plane curves, Fundamental groups of the Complements, Zariski Pairs, Alexander polynomials and its generalization, theta-Alexander polynomials.This generalization plays an important role for the research of non-reduced degenerations of plane curves and Their fundamental groups.Tokunaga did a fundamentak research on dihedral covering over plane curves of degree 6 and Zariski pairs.Shimada did the research of fundamental groups over positive characteristic.
